Le Rosey, a 100% boarding school for ages 8 to 18, does not publish its fees online and advises applying between June and September of the year before entry.

Families searching for IB boarding schools in Switzerland soon find a long list of schools offering the International Baccalaureate Diploma with boarding, and that fees for a single year can exceed CHF 150,000 once extras are added. The headline figure is only part of the decision: what it includes, the age a school prefers new boarders to start and whether weekly boarding exists all change the real cost.

This guide compares the published 2026-27 fees of six schools in Vaud and Geneva, explains full and weekly boarding, and sets out the admissions timeline and the questions to ask.

Which Swiss boarding schools offer the IB Diploma?

All six schools below offer the IB Diploma Programme in the last two years, and each says so on its own website. They differ in size, ages and what sits alongside the IB.

School	Programmes	Boarding ages	Boarding fee 2026-27 (CHF)
Le Rosey, Rolle and Gstaad	IB Diploma or French bac	8 to 18	Not published online
Aiglon College, Villars	IB Diploma	Junior and Senior School	In a separate fee document
Leysin American School	IB Diploma, AP courses	Grades 7 to 12	128,000
Collège Alpin Beau Soleil, Villars	IB MYP, IB Diploma	Grades 6 to 12	137,040 to 148,440
Collège du Léman, Versoix	IB Diploma, IGCSE, Swiss Maturité, French bac	Grades 5 to 12	117,500
St. George's, Montreux	IGCSE, IB Diploma	10 to 18	103,900 to 132,400 full; 76,500 to 97,100 weekly

Figures are the full-year boarding fees on each school's 2026-27 fee page; extras and one-off charges are listed separately below. Not every Swiss boarding school teaches the IB: Brillantmont in Lausanne, for example, teaches IGCSEs, A levels and a US High School Diploma rather than the IB, and its fee page already shows 2027-28 boarding fees of CHF 99,600 to 116,000.

How much do IB boarding schools in Switzerland cost?

For the two IB Diploma years in 2026-27, published full boarding fees at these schools range from CHF 117,500 to CHF 148,440 a year, and the first year costs more because of one-off charges and deposits.

Le Rosey

Le Rosey is a 100% boarding school with a main campus in Rolle and a winter campus in Gstaad. Every student follows a track to the full IB Diploma, in English, French or both, or to the French baccalauréat; the school reports an average IB score of 36 points against a world average of 30. It does not publish fees on its website, takes no donations and offers partial financial aid only, with a CHF 500 application fee. It warns that places for the last two years are scarce and does not recommend joining just for the IB.

Leysin American School

LAS in Leysin runs from Grade 7 to Grade 12, with the IB Diploma and Advanced Placement courses, and reports a 2025 IB average of 35 with more than 40 Higher and Standard Level courses. Its 2026-27 tuition of CHF 128,000 covers all classes, seven-day room and board, the winter ski pass, a laptop, the school health plan and the Swiss residence permit. New students add a CHF 500 application fee, a CHF 10,000 refundable security deposit and a one-off CHF 10,000 capital improvement fee, and the school suggests CHF 10,000 a year for the personal account.

Collège Alpin Beau Soleil

Beau Soleil in Villars teaches the IB Middle Years Programme and the IB Diploma. Its 2026-27 boarding and tuition fee is CHF 137,040 for Grades 6 to 10 and CHF 148,440 for Grades 11 and 12. On top come CHF 26,460 of other annual fees, including medical insurance and expeditions, and CHF 8,490 for the annual trip except in Grade 12. New students pay a CHF 3,000 application fee, a CHF 6,990 uniform package and a CHF 15,000 refundable deposit, and the school says it offers no financial aid or scholarships.

Two more names belong on most shortlists. Collège du Léman in Versoix, near Geneva, charges CHF 117,500 for boarders in Grades 5 to 12, including health insurance, books and three mountain weekends, with exam fees billed separately. Aiglon College in Villars reports a 2025 IB average of 36.6 and says 76% of its students board; its fee page lists inclusions and deadlines, with the figures in a separate document.

Full or weekly boarding: which suits your family?

Weekly boarding means pupils go home at weekends; at St. George's it costs about 26% less than full boarding, but it only works for families living within reach of the school. Among the published fee pages above, only St. George's lists a weekly price.

St. George's International School

St. George's offers weekly and full boarding to boys and girls from 10 to 18, with IGCSEs and the IB Diploma. Its 2026-27 schedule shows the gap clearly: Years 6 and 7 cost CHF 76,500 weekly or CHF 103,900 full, and Years 12 and 13 CHF 97,100 weekly or CHF 132,400 full, plus CHF 1,500 a year in IB Diploma charges. New boarders pay a CHF 8,500 admission fee and a CHF 4,000 security deposit, and pocket money, medical insurance and uniform are excluded. Collège Champittet in Pully also offers weekly (five days) and full (seven days) boarding, with full boarding at CHF 112,000 for 2026-27. For how the two models compare in the UK, see our guide to boarding school costs: full vs weekly boarding explained.

A worked example: the first year in Grade 11

Using each school's published 2026-27 figures for a new Grade 11 boarder:

Leysin American School: CHF 128,000 tuition, CHF 10,000 capital fee, CHF 500 application fee and the suggested CHF 10,000 personal account make CHF 148,500, plus the CHF 10,000 refundable deposit.
Collège Alpin Beau Soleil: CHF 148,440 fees, CHF 26,460 other fees, CHF 8,490 trip, CHF 3,000 application and CHF 6,990 uniform make CHF 193,380, plus the CHF 15,000 refundable deposit.

The gap between the two headline fees is about CHF 20,000; the gap in the first-year bill is about CHF 45,000. Always ask for the full terms and conditions, not just the fee table.

How do admissions work, and when should you apply?

Apply roughly a year ahead, especially for entry at 14 or above. Le Rosey advises registering between June and September of the year before entry and makes decisions usually within two weeks of a complete file for younger applicants. LAS fees fall due on 1 April, or within 10 days of acceptance for later offers, and Beau Soleil requires Terms 1 and 2 to be paid by 15 April. Students from outside Europe may also need a visa, which Brillantmont says can take up to 12 weeks to process.

What should you compare before you choose?

Is the fee all-inclusive, or are insurance, trips, ski programmes and exam fees extra?
What are the one-off charges and which deposits are refundable, and when?
Does the school take new students into the two IB Diploma years, and on what conditions?
Which IB subjects run at Higher Level in your child's languages, and is a bilingual diploma possible?
Is weekly boarding available, and what happens at weekends for full boarders?
Who handles the visa and residence permit, and is it included?
How many nationalities are in each boarding house, and are there nationality quotas?

Frequently asked questions

How much does a boarding school in Switzerland cost per year?

For 2026-27, published full boarding fees at the IB schools in this guide range from CHF 117,500 at Collège du Léman to CHF 148,440 for Grades 11 and 12 at Collège Alpin Beau Soleil. Budget extra for insurance, trips, exam fees and pocket money, and for first-year charges such as the CHF 20,500 at Leysin American School, which includes a refundable deposit.

Is weekly boarding available in Switzerland?

Yes, at some schools. St. George's International School offers weekly and full boarding from age 10, and in 2026-27 Years 12 and 13 cost CHF 97,100 weekly against CHF 132,400 full. Collège Champittet in Pully offers five-day and seven-day boarding. Weekly boarding only suits families who can collect their child every weekend.

Can international students join a Swiss boarding school for the IB Diploma years only?

Some schools accept new students into the last two years, but places are limited. Le Rosey says it is possible but does not recommend it, because demand for its IB course is highly competitive. Students from outside Europe may also need a visa, which can take up to 12 weeks, so apply at least a year ahead.
